[英]gem install pg -v '0.17.1' not working for some reason
我正在尝试通过 AWS EC2 Linux 服务器中的 rails 应用程序“捆绑”。 我收到“pg”gem 的这个错误。 有人可以帮忙吗? 找不到解决办法。
这个 gem 'pg' 的版本是 0.17.1。
Ruby 版本为 ruby 2.3.1p112 (2016-04-26 修订版 54768) [x86_64-linux]
$ gem install pg

当我在centos
或ubuntu
上安装gem 'pg'
时,我遇到了一些和你一样的问题。
对于centos,你可以这样做:
yum install postgresql-libs
yum install postgresql-devel
然后再次运行gem install pg
。
在 Ubuntu 上,我需要运行:
sudo apt-get install libpq-dev
